Application April 2', 1934, Serial No 218,729

3 Claims. (01. 1937) r forming the subject matter of this application relates to hullextracting cleaner feeder gins; and is in the nature of an improvement on the hull U. S. application,

extracting unit disclosed in my Ser. No. 670,565, filed May 11.

1933 for a Hull extracting unit.

The main object of the present invention is to improve the efficiency of machines of the type described. in the aforesaid pending application by substituting for the saw cylinder of such device, a

cylinder covered with card clothing, the teeth of which are, of course, arranged much closer together than is possible with saws without materially increasing well as its cost.

Another object the weight of the cylinder, as

of. the invention resides in discharging hulls from the machine throughout the length of the cylinder and on to a discharge screw conveyor, in order to avoid the injury inherent in the usual method of spiraling hulls and cotton along the cylinder to a discharge outlet at one end of the cylinder.

The old method of spiraling discharge, cuts and breaks the hulls and causes the shale from the hulls to get into the lint, thereby injuring the lint; and in addition thereto,

twists the fiber and otherwise injures the sample. Other objects of the invention will :appear as the detailed description thereof proceeds.

In the drawing:

prises a casing 1 having an inlet opening 2 at its upper end designe or hulled. Immediately below the inlet openin 2;

d to receive cotton to be cleaned a pair of feed rollers 3 and i, rotatably mounted between the end ployed to direct t cleaner drum 5.

walls of the casing l, are emhe cotton to be cleaned onto a The cleaner drum 5 is mounted to rotate between the aforesaid end walls, and directs the cotton receivedfrom the feed rollers 3 and 4 through a passageway 6, controlled by a valve plate '7, to the hull extracting part of the machine. When the Valve plate? is closed, the

cotton is directed by the cleaner drum 5 along a screen partition 8 to a second passageway 9 leading to a second cleaner drum 10 mounted rotatably at the outlet hood 11.

A spout 12 pivotally connected to the hood l1 directs the cleaned cotton to the roll box of a cotton gin (not shown) When the by-p is directed to the of the machine.

ass valve '7 is open, the cotton hulling chamber 13 at the rear Suitably secured to the rear .wallll i of this chamber, are a series of oif-set members 15, 16 and 1'7, generally inclined toward a drum '18 which is covered with card clothing. The drum 18 is rotatablymounted between the end walls of thecasing and a deflector plate19 5 depending from the iramework'of the screenpartition 8 serves to direct the tufts of cotton adheringto the teeth of the card clothing downwardly against a brush 20 mounted to rotate between the end walls of the casing about an axis parallel to the axis of rotation of the drum 18. A screen partition 21 is arranged below the brush 20 and directs the cotton removed by. said brush from the card roll 18 upwardly against the cleaning drum 10 at the outlet of thecasing. Directly below the screen partition 21 there is detachably mounted a section22 in which there is rotatably mounted awiper 23, adapted to throw all dirt, sand and trash passing through the screen 21 into a trough 24 in which a spiral trash conveyor 25 is rotatably mounted.v I Y The inclined member 16, as previously described, is inclined toward the periphery of the drum 18, to direct the hully cotton against the drum 18 A valve plate 26, rotatably mounted at thelower end-of the inclined member 16, is angularly adjustable toward and from theperiphery of the drum 18 to Vary the extent of opening of the passageway 27 leading to a compartment 28 directly below the member. 18. This valve plate 26' may be adjusted to holdthe cotton, trash and hulls in the upper part of the machinefor a longer or shorter interval of time, depending upon the amount of foreign material to be removed, as well as to provide an opening, the size of which may be varied to suit the character of the hulls to be discharged.

The lower portion of the inclined. member 17 is curved to form a trough 29 under a spiked roller 30 which is arranged belowthe drum 18, and to one side of a diameter passing vertically through the axis of the drum. Directly above and to one side of the same diameter of the drum 18, there is rotatably mounted a stripper cylinder 31, having bars arranged to strip or knock'oif hulls and trash which may adhere to the cotton drawn up by the teeth of the card'roll 18. A stripper plate 32 is fixedly secured to the inner end of the screen partition 8 and is provided with teeth arranged to enter the spaces between the rows of bars 33 on the stripper cylinder. .This construction is quite similar to that of the corresponding elements disclosed in my aforesaid U. S. application.

The valve plate 26 is secured to a shaft 34,

casing 1. A link 38 is pivoted at one of its ends eccentrically to the disk 35. The other end of the link 38 is pivoted to one end of the lever 39.

having a handle 40 at its other end. The lever 39 passes slidably through a slot formed in a stop I plate 41 suitably secured to the flange 42 formed on the end wall 37 of the casing. The lower edge of the lever is provided with a series of notches 43 adapted to seat in one edge of the slot in the plate-41. There is nothingparticularly'novel in this lever adjusting mechanism; Any suitable means may be used to adjust the valve'plate 26 within the chamber 13 to vary the passageway 27 leading to the chamber closed at its lower end by the spike roller 30.

The spike roller 30 rotates in a direction opposite to the direction of rotation of the. drum l8, and is intended to discharge the hulls out of the machine throughout the entire length of the cylinder and onto the spiral'conveyor 25. The shape of the trough .29 is such asto cause the hulls to be thrown up forcibly against the bottom, of the drum 18, thereby causing any locks of cotton in the discharged material to impinge onand adhere to the card clothing of the drum 18. -The hulls and other foreign matter fall by gravity from the drum directly on to the endless conveyor 25 and throughout its length.

This discharge mechanism increases the capacity of the gins over that obtainable by prior construction in which the cotton and hulls are spiraled past the lower portion of the cylinder ties at one end than at the other, and also decreases its capacity. The cleaning capacity is also improved in the present machine since cotton is cleaned better when it is spread evenly over the screen. l

' While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

What I claim is: I
